Description

Technical Field

[0001] The utility model relates to the field of air - conditioning refrigeration equipment, in particular to an outdoor unit of an air conditioner and a top - blowing air conditioner using the same. Background Art

[0002] In the existing top - blowing outdoor unit of an air conditioner, in most models, the air guide ring and the fan blade are inside the condenser. By adopting the above - mentioned structure, the overall height of the outdoor unit of the air conditioner can be reduced, so that more outdoor units can be installed when loading into the cabinet. However, since the air guide ring and the fan blade are placed inside the condenser, the size of the fan blade is restricted. In this way, the size of the fan blade is relatively small. In the case of the same air volume, a higher rotation speed is required, which brings greater noise. In addition, since the air guide ring is placed inside the condenser, it will affect the air field at the top of the condenser, resulting in poor heat exchange efficiency of the fins at the top of the condenser.

[0003] Currently, in view of the existing problems, some manufacturers have chosen to place the air guide ring and the fan blade above the condenser. The limitation of this solution is that the motor is placed above the fan blade, and both the motor and the fan blade are inside the air guide ring, resulting in a longer stroke required for the air guide ring, making the overall height of the unit higher, thus increasing the actual volume of the outdoor unit of the air conditioner and being unfavorable for improving the loading capacity of the cabinet.

[0034] Please refer to Figures 1 to 4 , the present utility model provides an outdoor unit of an air conditioner, including a top cover 1, a heat exchange component 2 and a box body 3;

[0035] The top cover 1 includes a top cover housing 11, a motor bracket 12, a driving member 13 and a wind blade 14;

[0036] The heat exchange component 2 is disposed in the box body 3. Air inlets 31 are provided on the side walls of the box body 3, and an air outlet 32 is provided on the top of the box body 3. The top cover housing 11 is disposed at the air outlet 32, and the top cover housing 11 is provided with a wind guiding channel 110; the motor bracket 12 is detachably connected to the bottom of the top cover housing 11; the driving member 13 is disposed on the motor bracket 12, and the driving end of the driving member 13 is disposed on the side facing away from the box body 3; the wind blade 14 is assembled on the driving end of the driving member 13, and the wind blade 14 is located in the wind guiding channel 110.

[0037] The outdoor air conditioner places the fan blade 14 above the condenser 21, so that the size of the fan blade 14 is not restricted by the internal size of the condenser 21 inside the box body 3. Therefore, when the size of the box body 3 is the same, the diameter of the fan blade 14 is increased by 40-70 mm, improving the air volume and energy efficiency of the fan blade 14; in the case of the same air volume, there is no need to increase the rotation speed of the fan blade 14, thereby reducing the noise generated during the operation of the fan blade 14. At the same time, the driving member 13 is fixed below the top cover shell 11 through the motor bracket 12, and is located below the fan blade 14 and above the heat exchange assembly 2, making rational use of the space, preventing the top cover shell 11 from increasing in height due to the need to accommodate the driving member 13, thereby avoiding the overall height of the outdoor air conditioner from increasing, resulting in an increase in the actual volume of the outdoor air conditioner and affecting the cabinet loading capacity of the outdoor air conditioner.

[0038] In a specific embodiment of the present invention, the driving member 13 is specifically a fan motor. The driving member 13 drives the fan blade 14 to rotate, thereby generating gas flow and discharging the hot air in the box body 3 from the air outlet 32; at the same time, the cold air located on the side wall of the box body 3 is affected by the air flow, enters the inside of the box body 3 from the air inlet 31, and exchanges heat with the heat exchange assembly 2 to become hot air; subsequently, it is discharged from the air outlet 32 again.

[0039] Specifically, the motor bracket 12 includes a fixed platform 121 and a connecting bracket 122;

[0040] The connecting bracket 122 is detachably connected to the bottom of the top cover shell 11. The fixed platform 121 is centrally arranged on the connecting bracket 122. The driving member 13 is arranged on the fixed platform 121, and the axis of the driving end of the driving member 13 coincides with the axis of the longitudinal direction of the box body 3.

[0041] The axis of the driving end of the driving member 13 and the axis of the longitudinal direction of the box body 3 are on the same vertical line, so that the rotation axis of the fan blade 14 coincides with the axis of the longitudinal direction of the box body 3. With the above structure, the driving member 13 and the fan blade 14 are centrally arranged, which is convenient to form a uniform air field inside the box body 3, so that the condenser 21 inside the box body 3 can pass through the same air volume everywhere, avoiding the situation of different heat exchange efficiencies on the condenser 21.

[0042] Specifically, the connecting bracket 122 includes two or more connecting rods 1221. The two ends of the connecting rod 1221 are respectively connected to the bottom of the top cover shell 11. The connecting rods 1221 cooperate with each other to form an installation area, and the fixed platform 121 is arranged in the installation area.

[0043] By adopting the above connecting rod 1221, the shielding of the top air outlet 32 is reduced, enabling hot air to smoothly pass through the air outlet 32 and be discharged, preventing hot air from accumulating inside the box body 3 and reducing the heat exchange efficiency. In a specific embodiment of the present utility model, two connecting rods 1221 are provided. The two ends of the connecting rod 1221 are respectively connected to the bottom plate 112, and the middle parts of the two connecting rods 1221 cooperate with each other to form an installation area for the fixed platform 121.

[0044] Specifically, the top cover housing 11 includes a wind guiding ring 111, a bottom plate 112, a surrounding plate 113, and a panel 114;

[0045] The bottom plate 112 is detachably connected to the outer edge of the air outlet 32. The surrounding plate 113 is wound around the outer edge of the bottom plate 112, and the panel 114 covers the top surface of the surrounding plate 113. The bottom plate 112 is provided with a first through hole, and the panel 114 is provided with a second through hole. One end of the wind guiding ring 111 is connected to the first through hole, and the other end of the wind guiding ring 111 is connected to the second through hole. The first through hole, the inner side wall of the wind guiding ring 111, and the second through hole cooperate to form a wind guiding channel 110. The bottom plate 112, the inner side wall of the surrounding plate 113, the outer side wall of the wind guiding ring 111, and the panel 114 cooperate to form an accommodation space 115. The motor bracket 12 is detachably connected to the bottom plate 112.

[0046] The bottom plate 112 functions to connect the air outlet 32 of the box body 3 and the connection support 122. The bottom plate 112, the inner side wall of the surrounding plate 113, the outer side wall of the wind guiding ring 111, and the panel 114 cooperate to form an accommodation space 115, which can be used to install electrical components, thereby saving the space of the electronic control box cavity and providing a larger maintenance and operation space. The first through hole, the inner side wall of the wind guiding ring 111, and the second through hole cooperate to form a wind guiding channel 110, enabling hot air to be discharged from the air outlet 32 along the wind guiding channel 110 to the outside of the box body 3.

[0047] Preferably, the top cover housing 11 further includes a mesh cover 116, and the mesh cover 116 is detachably connected to the second through hole.

[0048] With the above structure, while enabling air flow exchange between the second through hole and the outside, the shielding of the second through hole is achieved, thereby reducing the situation where external foreign objects fall into the inside of the top cover housing 11 and the inside of the box body 3 through the second through hole.

[0049] Further, the heat exchange assembly 2 includes a condenser 21 and a compressor 22;

[0050] The compressor 22 is disposed in the box body 3. The condenser 21 is disposed on the outer periphery of the compressor 22. A pipeline is connected between the heat exchange outlet of the compressor 22 and the heat source input end of the condenser 21. A pipe connection is made between the heat exchange inlet of the compressor 22 and the cold source output end of the condenser 21. The condensation outlet and the condensation inlet of the compressor 22 are respectively connected to the outside through pipelines.

[0051] For the structures of the condenser 21 and the compressor 22, the connection manner therebetween, and the working principle, reference can be made to the condenser and the compressor of the existing outdoor unit of an air conditioner, which will not be elaborated herein. The condenser 21 is disposed on the outer periphery of the compressor 22. After air enters the box body 3, it passes through the condenser 21 for heat exchange and moves closer to the middle; subsequently, the air is drawn into the air guiding channel 110 by the air blade 14 and discharged from the air guiding channel 110. With the above structure, the heat exchange efficiency can be improved.

[0052] Furthermore, the heat exchange assembly 2 further includes an electric control unit, and the electric control unit includes a water baffle 231, an electric control box 232, an electric control main board 233, and an electric control radiator 234;

[0053] The lower end of the water baffle 231 is connected to the bottom of the box body 3, and the upper end of the water baffle 231 is connected to the top of the box body 3. The electric control box 232 is disposed on the water baffle 231. The electric control main board 233 is disposed in the electric control box 232, and the electric control main board 233 is electrically connected to the compressor 22; the electric control radiator 234 is disposed inside the electric control box 232;

[0054] The condenser 21 and the water baffle 231 cooperate to form an enclosing structure, the compressor 22 is located in the enclosing structure, and the top cover 1 is located above the enclosing structure.

[0055] The water baffle 231 and the condenser 21 surround the outer periphery of the compressor 22. Air needs to pass through the condenser 21 before it can be drawn into the air guiding channel 110 by the air blade 14, which improves the heat exchange efficiency between the air and the condenser 21.

[0056] The electric control box 232 is used to protect the electric control main board 233. The electric control main board 233 is used to control the start or stop of the compressor 22, and the electric control radiator 234 is used to dissipate heat from the electric control main board 233.

[0057] The present utility model further provides a top-outlet air conditioner, and the top-outlet air conditioner includes the above-mentioned outdoor unit of an air conditioner.

[0058] The top-outlet air conditioner adopts the above-mentioned air conditioner outdoor unit, which not only solves the noise problem caused by the fan blades 14 being limited by the internal size of the condenser 21 in the box body 3, but also can reasonably utilize space, avoiding the problem of the top cover shell 11 needing to increase the height due to the need to accommodate the driving component 13, thereby avoiding the overall height increase of the air conditioner outdoor unit, resulting in an increase in the actual volume of the air conditioner outdoor unit, affecting the cabinet installation amount of the air conditioner outdoor unit.

[0059] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
